Exploring Ultra Lightspeed Communication using Relativistic Non Localization

Published Jan 1, 2021• 0 citations

Abstract

This paper, the tenth in the series of ‘Rudiments of relativity revisited’, explores superluminal communication based on relativistic non-localization of new relativity. The new relativity preserves the lightspeed like the current one but also digs deeper into the mechanism behind this constancy. The relativistic non-localization as a superstate is one of the explanations: a photon exists in a superstate of relativistic non-localization, which collapses on detection such that the lightspeed is preserved in the frame of detection. Is it possible to trick this mechanism for the light to supersede its own speed using one or more cross-frame interruptions meant to collapse its superstate in one frame and relaying another burst of light to be detected in another? The two subsequently relayed light-bursts individually preserve lightspeed in their respective frames of detection, but the net result of the two cross-frame flights can be fast or slow travel in a vacuum. Various caveats, assumptions, and experiments to explore supra or infra luminal communication under new relativity are discussed.

Relativistic Interferometer and Lightspeedometer Based on Relativistic Nonlocality

Gajendra Singh Solanki

This paper, the eleventh in the series of rudiments of relativity revisited, extends our efforts to speed up or slow lightspeed in a vacuum using relativistic non-localization of new relativity. In the previous paper namely ‘Ultra lightspeed travel using relativistic non-localization’ we had developed theory and experimental setups to realize supra and infra lightspeed travel. However, all the experimental setups were bulky to realize and their sensitivity was also low. In this paper, we design a highly sensitive interferometer and a lightspeed manipulator that work on the presumption that reflection or refraction may lead to the total collapse of the relativistic non-localized state of a photon, and the reflected or refracted beam bears no memory of the relativistic non-localized state of the incident beam.

Relativistic Non-Localization: An Ignored Reality

Gajendra Singh Solanki

Relativistic non-localization enables a moving particle such as a photon to exist at different positions in different frames at an instant and gives rise to an experimentally distinguished physics of relativity. A photon exists in a relativistic non-localized superstate until it is encountered by a detector which results in the collapse of the superstate so as to preserve the lightspeed across frames because the motion state of the detector affects the position of detection. But the current relativity inadvertently assumes the photons to be relativistically localized and invents the relativity of simultaneity. The relativistic non-localization, which is the nonlocality across frames, remained hidden so far under the mathematical elegance of Lorentz transform but is readily revealed by the real domain transform.

Quantum Entanglement and Superluminal Particles: Preservation of Causality under Relativistic Constraints

Hasan Efe Karabulut

Two statements in physics are frequently conflated: that nothing can travel faster than light, and that two entangled particles behave as if "instantaneously" connected regardless of their separation. This paper addresses both questions together: whether a faster-than-light particle could exist and, if so, whether it would count as matter; and whether quantum entanglement actually violates the light-speed limit. Starting from the energy–velocity relation of special relativity, it is shown that massive particles cannot reach the speed of light, and the properties of hypothetical tachyons (imaginary mass, absence of a rest frame and violation of causality) are examined. Using the singlet state, the non-separability, reduced state and correlation properties of entanglement are derived, and the quantum violation of the CHSH inequality up to 2√2 is computed. Finally, via the no-signaling theorem, it is shown that entanglement produces non-local correlations without permitting superluminal communication. In conclusion, nature accommodates non-local correlations without allowing any object to travel faster than light.

Superluminal quantum reference frames

Amrapali Sen, Matthias Salzger, Łukasz Rudnicki

Abstract Particles cannot travel faster than the speed of light, nor can information. Nonetheless, this assumption has been frequently questioned over the years. This includes radical proposals like tachyons that can be observed in particle accelerators to more subtle ideas like studying superluminal causation to find classical explanations for quantum correlations. Most recently, it has been argued (Dragan and Ekert 2020 New J. Phys. 22 033038) that in a world with superluminal observers local determinism is impossible, linking the two pillars of physics-quantum theory and relativity-suggesting that the latter serves as the foundation for the former. Motivated by this approach, in this work, we extend the framework of quantum reference frames to incorporate superluminal Lorentz transformations. We apply this conceptual result to examine an apparent paradox where particles acquire negative energies after undergoing a superluminal Lorentz boost and propose a resolution within our framework. A consequence of this resolution is that different observers no longer agree whether a particle is incoming or outgoing or in a superposition of the two. We further find a similar apparent paradox for the entropy and/or temperature under superluminal Lorentz boosts and resolve it in an analogous fashion. Finally, we discuss Bell experiments under superluminal quantum reference frame transformations, showing that the involved probabilities still remain conserved. By applying the toolbox of quantum reference frames, we start charting an unexplored territory of superpositions between sub-and-superluminal quantum observers which gives rise to new conceptual questions.

LOCAL CAUSALITY AND THE FOUNDATIONS OF QUANTUM MECHANICS

Robert S. Goldstein

Quantum mechanics implies the existence of correlations which cannot be described by any local theory. These nonlocal correlations possibly suggest the existence of particles traveling faster than light (tachyons). But the potential paradoxes associated with their existence imply that, even i f these tachyons do exist, it should not be possible to control them in a manner necessary for human superluminal (faster than light) communication. Indeed, the unitary nature of the time development operator precludes the possibility of using non-local correlations to communicate superluminally within the quantum formalism. A simplified model which preserves unitary time development i s shown to be useful in studying 'thought experiments' which appear init ially to allow for superluminal communication. The consistency of quantum mechanics is questioned when measurements of retarded fields are considered. I f certain idealized measurements are possible in principle, then the quantum formalism appears inconsistent. I f the measurements are not possible in principle, then 'state reduct ion' (non-unitary time evolution of the state operator) in a pragmatic sense can be said to have occurred. The suggestion that tachyons be used to explain the non-local correlations i s abandoned in favor of another model whose philosophy is supported by the tenets of relativity theory. Such a model may imply the existence of a more general quantum theory where a quantum system itself can be taken as a (generalized) frame of reference.

In search of superluminal quantum communications: recent experiments and possible improvements

B Cocciaro, S Faetti, L Fronzoni

As shown in the famous EPR paper (Einstein, Podolsky e Rosen, 1935), Quantum Mechanics is non-local. The Bell theorem and the experiments by Aspect and many others, ruled out the possibility of explaining quantum correlations between entangled particles using local hidden variables models (except for implausible combinations of loopholes). Some authors (Bell, Eberhard, Bohm and Hiley) suggested that quantum correlations could be due to superluminal communications (tachyons) that propagate isotropically with velocity v t > c in a preferred reference frame. For finite values of v t , Quantum Mechanics and superluminal models lead to different predictions. Some years ago a Geneva group and our group did experiments on entangled photons to evidence possible discrepancies between experimental results and quantum predictions. Since no discrepancy was found, these experiments established only lower bounds for the possible tachyon velocities v t . Here we propose an improved experiment that should lead us to explore a much larger range of possible tachyon velocities V t for any possible direction of velocity of the tachyons preferred frame.
